适用范围：This International Standard specifies the requirements of enamelled round copper winding wire of class 200 with a dual coating The un Jerlying coating is based on polyester or poly-esterimide resin, which may be modified providing it retains the chemical identity of the original resin and meets all specified wire requirements. Tne superimposed coating is based on polyamide-imide resin.NOTE — A modified resin is a resin that has undergone a chemical change, or contains one or more additives to enhance certain performance or application characteristics.Class 200 is a thermal class that requires a minimum temperature index of 200 and a heat shock temperature of at least 220°C.The temperature in degrees Celsius corresponding to the temperature index is not necessarily that at which it is recommended tnat the wire be operated and this will depend on many factors, including the type of equipment involved.The range of nominal conductor diameters covered by this standard is:— Grade 1: 0,050 mm up to and Including 2,000 mm— Grade 2: 0,050 mm up to and including 5,000 mmThe nominal conductor diameters are specified in clause 4 of IEC 317-0-1.
